The SWi 118E - SP is an active plug-andplay subwoofer and is an ideal extension to the passive K&F speakers and the active full-range systems of the K&F SP series. With a frequency range extending as low as 30 Hz and a maximum sound pressure level of 133 dB the SWi 118E - SP is equally at home as an outstanding bass system in theatres, cinemas or all-purpose halls or as a powerful and precise basic low-frequency set-up in discotheques and live clubs or as a compact P.A. High-quality self-powered systems can be assembled in parallel operation with the active SP
full-range systems. When supplementing the passive K&F full-range systems the SWi 118E - SP active subwoofer is driven separately.
The innovative, fan-free system electronics weigh only 2.5 kg and include the digital 1 kW Class D power amplifier and an elaborate limiter section (RMS and peak limiters). Here too the system
equalization, cut-off frequency and phase response are defined.
8 concealed M 12 thread inserts, which serve as variable flying points or can be used to attach supports or suspension frames, are standard equipment. The excellent performance data and
simple handling of the SWi 118E - SP set new standards in top class professional active subwoofers. Ideal for fixed nstallations of the highest standard.
